The way forward for TV tech is just a single OLED pixel extensive

Researchers on the Pohang College of Science and Expertise (POSTECH) in Pohang, South Korea have unveiled a prototypical OLED show with a doubtlessly game-changing twist: the novel 13-inch panel is able to emitting not solely visuals, but additionally full-blown audio.

In a analysis article titled Localized Sound-Built-in Show Speaker Utilizing Crosstalk-Free Piezoelectric Vibration Array, published in Advanced Science again in April 2025 (via ScienceDaily), Inpyo Hong and Su Seok Choi define a display that may basically convert electrical alerts into full-blown sound vibrations utilizing piezoelectric know-how.

“Piezoelectric speakers instantly convert electrical vitality into mechanical movement by way of the inverse piezoelectric impact, enabling environment friendly sound era with a light-weight, versatile, and low-power design. Their easy layered building, consisting of electrodes and piezoelectric supplies, provides benefits corresponding to low price, excessive vitality effectivity, and compactness,” write Hong and Choi.

What’s Pixel-Based mostly Native Sound OLED know-how?

A conceptual multi-channel sound system the place every pixel emits its personal audio

Dubbed Pixel-Based mostly Native Sound OLED know-how by the POSTECH researchers, a central innovation employed on this idea is the embedding of Piezoelectric exciters instantly into the body of the 13-inch OLED panel in query. This circumvents the necessity for conventional audio exciters, which take up a considerable quantity of bodily house to supply sound via their driver ingredient and different required speaker internals.

Piezoelectric tech itself is not new — we have seen shopper electronics manufacturers experiment with it up to now, corresponding to with the Google Pixel 5’s grill-less front-facing speaker hidden behind its show. This all-new implementation of Pixel-Based mostly Native Sound OLED tech is distinct, nonetheless, with its pixel-like association and embedding instantly into the OLED panel {hardware} itself. The top result’s an OLED display association that may produce audio at a per-pixel stage, very like how every particular person OLED pixel can already emit its personal mild.

In keeping with Hong and Choi, these piezoelectric exciters could be demonstrably built-in into the body of an OLED show with out considerably impacting the form and dimension of the panel itself, all whereas eliminating crosstalk (sound supply leakage) and bolstering acoustic precision, positionality, and localization.

Samsung’s new OLED tech will make TVs as thin as a credit card

Samsung has unveiled its new UT One OLED show know-how, which guarantees ultra-thin and energy-efficient shows sooner or later.

Is Pixel-Based mostly Native Sound OLED know-how the way forward for TV?

Price, manufacturing, scaling, and high quality are all obstacles that should be labored via

Conceptually, Pixel-Based mostly Native Sound OLED know-how is an thrilling prospect. OLED panels are already thought-about best-in-class for his or her skinny and versatile design, their per-pixel management of sunshine emission, and their deep blacks and punchy distinction ranges. The addition of pixel-perfect audio emission has the potential to bolster the coveted ‘ 3D spatial audio‘ or encompass sound impact that some shopper manufacturers try to attain, whereas additionally obsoleting cumbersome speaker {hardware} within the course of.

“This know-how has the potential to grow to be a core function of next-generation units, enabling glossy, light-weight designs in smartphones, laptops, and automotive shows – whereas delivering immersive, high-fidelity audio,” writes Hong and Choi within the analysis paper.

After all, the findings of Hong and Choi are experimental and function a proof of idea — Pixel-Based mostly Native Sound is not a consumer-ready know-how that may be churned out on a manufacturing line, and it possible will not be for the foreseeable future. To be able to obtain the dimensions obligatory for mass industrial manufacturing, audio efficiency should obtain cost-to-performance parity with present shopper audio units, and probably different hurdles will should be conquered.

There’s additionally no telling whether or not this tech will scale effectively to larger-screened and smaller-screened units, or whether or not piezoelectric exciters will in the end be capable to obtain the audio outcomes shoppers anticipate out of their TVs, smartphones, and different tech devices (present implementations of piezoelectric tech, corresponding to on the aforementioned Pixel 5, have not precisely taken the world by storm).

Personally, I am hopeful of a future wherein Pixel-Based mostly Native Sound not solely hits the patron house, but additionally achieves essential mass. Audio directionality and spacial contextualization can significantly elevate the expertise of consuming media, and that is double true in terms of augmented actuality (AR) and digital actuality (VR) headsets. If cumbersome traditional speaker hardware had been to someday grow to be antiquated, it’d additionally open up the door for even thinner tech merchandise throughout the board, which is an thrilling prospect certainly.
